To all whom, it may concern:

Be it known that 1', AUGUST 6. PETERSON, a citizen of the United States, residing at Victoria, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Car-Brakes, of which the following is a specification.

My invention relates to certain new and useful improvements in car-brakes, and it is more particularly intended for use as an emergency-brake for street-cars.

In the operation of street-cars it is frequently desirable that the car should be stopped suddenly and within a short distance to avoid accidents, and it is well known that with the ordinary brakes now in use, operated in some instances by a lever and in others by a crank, it requires considerable time comparatively for the operator to set the brake.

The primary object of my invention, therefore, is to provide an apparatus which can be connected with any ordinary brake-rigging and which is adapted to be operated at any time to set the brakes, the power exerted by this apparatus being supplemented simultaneously by the operation of the ordinary brake mechanism.

A further object of the invention is to provide a brake mechanism to be used preferably in emergency cases only and which can be combined with an ordinary brake-rigging of a car, the two apparatuses being capable of independent or conjoint operation.

Another object of the invention is to provide a supplemental brake apparatus for street-cars which can be set in position for operation upon the brakeshoes and remain in such position regardless of the operation which will be pointed out fully hereinafterin the detailed description and in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of a car having my improved brake apparatus applied theretoand shown in sideelevation. Fig.2 is a bottom plan view of a street-car, showing the brake apparatus. Fig. 3 is an enlarged bottom plan view showing an embodiment of my invention, the apparatus being in set position. Fig. 4; is a side elevation of the apparatus as shown in Fig. 3. Fig. 5 is a sectional view on the line 5 5 of Fig.3. Fig. 6 is an enlarged side elevation, partly in section, of the apparatus, showing the parts in the position they occupy when the power of the apparatus is applied to the brakes. Fig. 7 is a sectional view on the line 7 70f Fig.6. Fig. 8 is adetailed sectional view on the line 8 8 of Fig. 7.

Referring to the drawings, in which like letters of reference denote corresponding parts in all of the figures, A designates the body of any ordinary street-car, which is suitably supported on the carrying-wheels a on the axles a and provided with any preferred brake-rigging, designated generally by B, and comprising brake-shoes Z) of any suitable construction.

My improved emergency-brake apparatus is attached to the bottom of the car, prefer ably at or about the middle thereof, and it comprises a frame consisting of the sides 0 and ends 0, suitably fastened together and attached to the car. An upper arch D is secured to the ends 0, and between this arch and a lower arch d, also secured to the ends 0, the clutch mechanism by means of which the brake apparatus is set is arranged. This clutch mechanism comprises two members E and E, whose operative faces are provided with engaging lugs whereby the said mem: bers may be locked together at the proper time and released by separating the members vertically. The upper member E is rigidly secured on a collar 6, which is mounted on the vertically-sliding pin F and rigidly connected with a two-armed clutch-lever G, which lever is arranged loosely upon the sliding pin and located, in the embodiment of my invention illustrated in the drawings, above the upper arch D. The lower clutch member E is loosely secured on a collar g, fastened immovably to the lower arch d by means of a nut g and provided with a central opening, through which the sliding pin F operates. The sliding pin F is provided with a spline f, which extends through a groove f in the collar 9 and carries the lower clutch member E, so that said lower clutch member will be moved by and simultaneously with the pin, as hereinafter described.

The sliding pin F extends through the lower arch cl, the collar g and lower clutch member E, the collar 6 and upper clutch member E, the upper arch, the clutch-lever G, and is provided on its upper end with a spring cl, the tendency of which is to hold the lower clutch member up in engagement with the upper clutch member and the apparatus in set position.

The clutch-lever G has two arms extending to opposite sides of the frame of the apparatus, each arm being connected with mechanism of the same general character, only one of which need be describedspecifically. A bolt II is arranged to slide in the ends 0 of the frame, and it is provided at one end with a spring 72.,which is inclosed between the headed end 7L of said bolt and one end 0 of the frame, and preferably inclosed within a casing J to protect the spring from injury and dirt. A platej is pivotallysecured on a collarLrigidly fastened to the bolt H between the ends of the frame, one end of said plate being connected by a link j wit-h the clutch-lever G and the other end of said plate being provided with a groove and operating onthe guiding-pin 2'.

The clutch-lever is operated by means of the pull-bar K, said pull-bar being provided with a slot 7c, and the end of the clutch-lever also having a slot is, through which slots a bolt L passes. The pull-bar is held in place by means of a guiding-plate I, also provided with a slot Z, this plate being secured in place at the sides of the frame and below the pullbar, so that in the operation of setting the apparatus when the pull-bar is drawn out it will slide along above the guide-plate Z and carry with it the clutch-lever G, by reason of the connection formed by the pin L, which passes through the slots in the plate 1, the pull-bar K, and the cl utch'lever G. After the apparatusis set in position for operation-that is to say, when the upper clutch member E has been turned to such position that the spring cl will carry up the pin and the clutch member E into engagement with the upper clutch member Ethe pull-bar K can be released and return to its normal position, the slot therein providing for its return without disturbing the position of the clutch-bar, which bar and its connected parts are locked in position by the clutch members.

A bar If is connected to the plate j and to the brake-riggin g in such a way that whenever the clutch mechanism is released and the bolt 11 is thrown backward by the spring h the power of said spring will be communicated through the bolt, plate, and connecting-bar to the brake-rigging and the brake-shoes to set the shoes into contact with the wheels. The mechanism for releasing the clutch and throwing the apparatus into action consists of alever N, pivoted at n and having one end provided with a push-bar O and its other end bearing upon the head 0 of the sliding pin F.

The operation of my improved apparatus is very simple and will be readily understood from the foregoing description, taken in connection with the drawings. To set the apparatus, it is only necessary to draw the pull-bar K forward, and this can be done in any way by means of a lever or crank device or in any manner preferred. In drawing the pull-bar forward the end thereof engages the pin L and carries it forward, thereby swinging the lever G and carrying the upper clutch member E around from the position shown in Fig. 6 to such position as will permit the faces of the clutch members to interlock, as shown in Fig. 4-, the spring (1 carrying the pin and the lower clutch member rigid thereon upward until said members are locked together. Then the parts have been locked together in this position, the pull-bar may be released and returned to its normal position.

To apply the power of the apparatus to the brakes, it is only necessary to disengage the clutch members, which is accomplished by pressing on the push-bar O and depressing the other end of the lever N to force the sliding pin downward, overcoming the tension of the spring (1 and disengaging the lower member from the upper member of the clutch. When this is done, the clutch-lever swings back to its normal position under the influence of the springs h, and these springs also carry back the bolts II and the plates f, and through the medium of the connecting-bars M their power is applied directly to the brake-rigging and the brake-shoes.

It will be observed that this apparatus can be operated from either end of the car, as it is provided with pull-bars on opposite sides, attached to the same mechanism and adapted to be operated at any time independently of each other. When the clutch is unlocked, both of the springs 71, exert their power upon the brake'shoes.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
